Nah my man. No excuse to act like an ass like that; life’s work or not. That’s simply a sign of poor emotional maturity, and is (plain and simple) abusive behavior. People make mistakes, regardless of the severity of the mistake. Let’s put it another way: would you be okay with someone talking to a child that way? If not, why is it okay to do so to an adult? Just because we’re older, doesn’t mean we deserve it.
